5.7.2 Turning the Valve ON/OFF
By activating the valve at station 7, the vacuum within the nozzle
switches from off to on (the spool is pushed) and at the same time
the air that turns on the vacuum generator is supplied. By turning
the valve off, the vacuum within the nozzle is destroyed and part
placement is made possible.
When the valve is turned on the inside of the nozzle becomes a
vacuum which enables the nozzle to pick up a part.
The operation of turning the valve on and off is driven by a cam
mechanism. The cam drives a lever, which drives a rod, which
drives a lever, which drives the slide.
The stroke of the rod is a fixed value determined by the curve of the
cam.
Fig. 5-37 Valve Activation Operation Mechanism at Station 7
Follow the procedure below to adjust the activation and
deactivation of the nozzle valve.
(1) Press [SET], [MANUAL], [I/O] and [EMERGENCY STOP] to
cut the 200V power supply but still leaving the 100V power
supply on.
(2) Enter the I/O map and press [OUT], [+Page] then use the [▼]
or [▲] key to move the cursor to the item titled “Y028 PLACE
SOL ON”.
(3) Make sure the spool is pushed in.

(4) Using the [ON/OFF] button, change the displayed “X” to “O”.
This allows the stopper to be removed enabling the shaft to
move vertically.
(5) Attach the cam handle to the cam shaft. Turn the handle until
the cam angle indicator reads 270°.
(6) Adjust so that the gap between the pushed in spool and the
pusher is 0.1 ~ 0.3 mm.

(7) Return the cam angle to 0°. Confirm that the gap between the
pulled out spool and the pusher is more than 2 mm. To adjust
the air release valve, tighten the knob completely, then turn it 5
to 5.5 revolutions.

5.8 Station 8
Station 8 has no function.
5.9 Station 9
Station 9 performs a nozzle vertical position check to confirm the position
of the nozzle after part placement. In addition, nozzle holder A is
checked and the information obtained is used as production data.
5.9.1 Nozzle Vertical Position Check
After the station 7 nozzle drops, sensors check whether or not it
returns to its original position. The check made by these sensors is
called the nozzle vertical position check. If the nozzle does not
return, the machine stops immediately to prevent damage from
occurring at the next stage.
